I read a lot of complicated stuff about cleaning the print head after my similar problem this week. Finally I found an old, soft toothlbrush, gave it a very light spray with windex and lightly brushed the magenta print head. I put the cannon cartridge back in and everything is printing perfect again. This worked for me, good luck to l you.

Colors not matching computer


It is possible your colour cartridge has cross contaminated the ink reservoirs. To check this take the colour cartridge out and turn it over to see the coloured pads. They should look red, dark blue, and orange ( the colours are actually Magenta, Cyan, and Yellow, but are concentrated). If any of the pads are pale or particularly green - change the cartridge.
If the colours look alright, your issue is probably that your monitor makes colour by emitting light frequencies so is bright, printed images make colour by absorbing light frequencies so will always be darker. There is always the issue of course that your monitor also has a colour "temperature" bias. Photo pros calibrate their monitors and printers to match.

My printer is hp laserjet cp 1515n. After printing some documents it writes "printing cool down mode" and begins working very slowly. Please help me


1515n - I have the Magenta colour 'shadowing' the blue test. A mirror image of the blue text. [slightly staggered] Black is fine. Applies to all Word docs when printing in blue - can you help please?
I only use genuine cartridges.
Thanks

Why doesn't my A920 injet print colors properly--green comes out pink, and I still have half the ink left in my color cartridge.


1) Could be your printer settings, check out your printer preferences to make sure your not printing a negative or make sure you colour corrections is enabled.

2) If the colour cartridge is a 3 in 1, just one of the colours may have run out. Giving a distorted picture. That means a new cartridge. The best way to check that is to go to your printer tool box and print out a test sheet. There should be 3 colours (Magenta, Yellow and Blue) and Black. If one's missing, the cartridge is out one colour.

What does it mean when it says change k cartridge


There should be four ink cartridges inside the printer: Cyan, Magenta, Yellow and blacK.

While monitors build colours out of three emissive (active) base colours, red, green and blue, printers usually build them out of four absorbing (passive) inks, so-called CMYK. The black is referred to by its last letter to avoid confusion with Blue.

On most printers, since they usually print in black ink over white paper (and black is used to darken all other colours), the K cartridge is either bigger than the others, or needs to be replaced more often.

My Dad's 3210xi all of a sudden prints pictures in blues & greens


Occasionally printer cartirdges can clog and become unusable after refilling them several times. Also, if a printer cartridge has been "dry" for a long period it may experience the same problem. Your best bet is to buy replacement cartridges for any colours that show problems on the test page. If there is a blue & green hue to your printing that would suggest that the magenta is not printing and should be replaced.

I have a used C60. I have replaced both ink cartridges with Epson cartridges. When printing in color, the colors are not accurate. For example, red comes out yellow. Also, there are lines running through...


Hi there. The reason for your problem is that the colour cartridge contains cyan, magenta and yellow ink, plus a black cartridge of course. All the other myriad colours are produced by mixing these four basic colours. So, if you print red, it requires ink from both the magenta and yellow cartridges. Thus if your red produces a yellow print, it means your magenta is not printing. This can be due to a number of reasons, mainly an empty or faulty magenta cartridge or blocked magenta print nozzles.

If you wish me to help you with sorting out the lack of magenta, please post a new comment to this effect.
